To all whom, fit 'may concern.'

e ,it known that d, CARTER il. ll u'r'i's, n citizen oi the UnitedStates, residing ,et Boston, inthe county of Suffolk end State ofMassachusetts, have invented e new end useful Aiitoxnobil`i'l`ire,lowingl is e specification.

j'lhe invention releztes ito iinj'nfovements in tires` for nutomobilesand similar vehicle f equipped with springs nrrenged to forni aprotecting armor, vand capable voi lproducingA a highly resilient Itire`and adapted to be constructed of suflicient strength to cerrythe load,whereby the tire vmuy be used .either with or Awithout an inner tube.

lilith these sind other objects in View, the invention consists in theconstruction und novel combination of parte hereinafter fully described,illustrated in the ecconijni-nyingT drawing, end pointed out in theclaims hereto appended-g yit bei-ng understood that various changes inthe form, proj'iontion, size und minor details of coi'istructiou,"Within the scope of the clein1s,n1ay be rf-ssorte'd to `withoutdeparting from the sjgiirit or sacrificing' any of' the advantages ofythe invennon.

but they may beef elly-other preferred construction. By .ineens of theoverlapping interlocking' ijoint. shown in Fig. l, the meetinglongitudinal edges 3 et the center of the buse ere `i'rmintstined ininter-locked lrele- The interior of the tire :is substantially circularin cross section to adapt it tor ithe reception of en yinner tube, andthe .tire is provided with en inner tubular 'lining il of rubber, butany other suitable materiel may be .employed in the rconstruction of`the inner lining of the ftire.

The mein bodjyr portion ofthe tire is composed of two llayers 5 sind 6,urreugediinteriorly .end-exteriorly of inner and outer series 7 end 8Yof Ithe springs and enveloping the seme; The inner end outer ,layers 5sind G nre designed to -be constructed of cnnvas or other suitableicebrio lwhich is preferably lprovided with sutlicient rubber `to enablethe material -of the tire to -be vulcanized or otherwise united `into Aesingle piece or one solid mass. The ,inner und outer tahric layers 5 and6 are preferably united et the inner attaching portieri or base oit' the*tire7 und llongitudinal annuler strips 9 .of any suitable vmateriel-ure preferably arranged within the fabric layers to forni the sidebends -or ribs 2. Y

The springs '.7 -and `8 nre arranged in e circumferential series andentend around the tire transversely thereot, end their terminals 10 and.l1 ere curved -outwnrdly or hook-shaped und ventend into the sidolin-nds or ribs 2f The inner series -ot springs T :un arranged side byside to forni :i complete metallic protecting'arinor for the tire2 undthe outer series 8 are arranged ou the inner series and break jointswith the seine7 the springs of the outer series covering' the side edgesof the springs oi the inner series. ly this arrangement the springs nreadopted to c'lliectiuilly prevent en inner inflatable tire trom beingcut or puuctured. rThe springs ere Vtapered to enable them to lit.snugly together, and they are arranged WithinI fabric coverings orcasings 12 of canvas, or other suitable material. The fabric casings ofthe springs a're adapted to prevent the metal from cutting, wearing orotherwise injuring the adjacent portions of the tire. The springs may bevaried in thickness and may be Constr ucted of sufficient strength tocarry \the'lfad, and thereby obviate the necessity of employingan'inner' inflatable tube, but when the tire is equipped with an innertube, the springs are relatively light to render the ou r casing highlyresilient.

The layers 5 and 6 are preferably of uniform thickness around the tire,and the lat-4 ter is provided with an intermediate section 13, taperingin thickness from the center of the tread portion of the tire to thesides thereof, and composed of layers of transversely disposed taperingstrips 14 of fabric, which successively decrease in length from theinner layer to the outer layer l5, the strips of which are of uniformlength with the strips of the inner layer. The strips are arranged inoverlapping relation, so that the strips of each layer or series overlapthe side A'edges or break joints with the strips of the contiguousseries or layers. The flexible fabric strips are designed to besaturated or impregnated with a suitable material to render them rotproof, and the intermediate section ,13 is arrangedwithin a continuousfabric covering 16 of canvas, or other suitable material, extending fromone side of the tire to the other and forming an exterior covering orcasing for the flexible strips, and designed also'to be saturated orimpregnated With a material for rendering it rot proof.

- The tire/is equipped with a transversely tapered tread section 17designed to be constructed of rubber', or rubber and fabric, and it maybe exteriorly corrugated in any desired manner to prevent the tire ,fromslipping or skidding.

In the construction of the sections or layers of the tire, asbestos maybe substituted for fabric or used' in connection with the same.

Having thus fully described my invention, What I claim as new and desireto 'secure by Letters Patent, isz- 1. A tubular tire including an innertubular body portion, an intermediate sect-ion consisting of layers ofllexible'transversely disposed strips arranged in overlapping resideportions extending from the thickenedv portion to the base of the tire,and an outer tread section substantially coextensive with theintermediate section.

2. A tubular tire including an inner tubuf lar body portion, aintermediate section consistingof layers of flexible transverselydisposed strips arranged in overlapping relation and successivelydecreasing in length to the outermost layerl and the strips of thelatter being of substantially uniform length With the strips of theinnermost layer, a continuous fabric casing covering the intermediatesection and extending lfrom one side of the tire to the other, and anouter tapered tread section substantially coeXtensive with theintermediate tapered section and having side portions tapered from thetread of the tire to the base thereof and terminating at opposite sidesof the same.

3. A tubular tire including an inner tubular bodyv portion consisting ofinner and outer tubular layers extending inwardly and outwardly atopposite sides of the base of the tire and having bottom connectingportions forming beads, the outer portions or Walls of the beads beingthickened, springs arranged between the inner and outer layers of thebody portion to form a metallic armor and having outwardly curvedterminal portions` extending partially around the said beads at theouter walls thereof and em-y bedded in the enlargements of the same, anintermediate tapered section consisting of layers of flexibletransversely disposed strips arranged in overlapping relation andsuccessively decreasing in length to the outermost layer and forming athickened outer portion at the tread of the tire and inwardly taperedside portions, which terminate at the ends of the said springs, and anouter or' tread section substantially.coextensive with the intermediatesection.

In testimony, that I claim the foregoing as my own, I have heretoaffixed my signature inthe presence of two Witnesses.
